Versuchsvorschrift

A solution of methyl 2-chloro-4-methyl-6-(3-methyl-1-tosyl-1H-indol-4-yl)nicotinate (0.348 g, 0.742 mmol) in DMF (5 mL) was sparged with argon for 10 min before trans-Pd(PPh3)2Cl2 (0.052 g, 0.074 mmol), tri-n-butyl(vinyl)tin (0.353 g, 1.11 mmol), and BHT (0.016 g, 0.074 mmol) were added. The resulting suspension was sparged with argon for 5 min and the vessel was sealed and heated at 60° C. After 24 h the reaction was allowed to cool to rt and 50% KF on Celite® was added. The resulting slurry was then filtered over Celite® eluting with EtOAc. The organic was then washed with 10% KF in water and then dried (Na2SO4), filtered and concentrated. The residue was then purified by FCC (5-40% EtOAc/heptane) to give the title compound. MS ESI m/z 461.1 (M+H)+.
